When Justin Timberlake came through Philadelphia with Jay Z on the Legends of Summer Tour in August, he had a new album, “The 20/20 Experience,” that debuted at No. 1, a hit (“Suit & Tie”) that peaked in the Top 5 and was falling and another (“Mirrors”) that was on its way up the chart.

Three months later, Mr. J.T. is coming back through the city on a solo tour, and he has another new album, “The 20/20 Experience — 2 of 2,” that debuted at No. 1, a hit (“Take Back The Night”) that peaked and another (“TKO”) on its way up.

Meantime, the earlier songs, “Mirrors” and “Suit & Tie” all went double platinum. Any wonder he’s the Top Concert of the Week again?

Two and a half years ago, alt-pop band Paramore’s future was in question. Its lead guitarist Josh Farro, who wrote all of the band’s platinum 2007 album “Riot!” and most of its 2009 gold, No. 2 album “Brand New Eyes,” left the band with drummer brother Zac, in an acrimonious split.

The release of Paramore’s self-titled fourth album in April washed away those concerns. Singer Hayley Williams and guitarist Taylor York, now playing lead, have written the band’s most accessible disc yet, giving the band its first chart-topping disc and its first Top 10 hit with “Still Into You.”

There was a time when The Byrds singer and guitarist Roger McGuinn and country singer Marty Stuart were seen as being at opposite ends of the music spectrum. But since The Byrds’ heyday in the mid-1960s, genre lines have melded and blurred so much that putting the two on the same show now makes sense.

Both men are partially responsible for that blurring. McGuinn and The Byrds meld folk and rock with such mid-1960s hits as “Mr. Tambourine Man” and “Turn! Turn! Turn!” Stuart is know for his eclectic merging of rockabilly, honky tonk and traditional country music with early 1990s hits “Hillbilly Rock” and “Little Things.”

Since his late 1970s start as a new waver, Elvis Costello has had great success with backing bands such as The Attractions, with whom he was inducted into the Rock and Roll Hall of Fame in 2003, and The Imposters, and has performed collaborations with artists ranging from Burt Bacharach (with whom he won a Grammy in 1999) to the Beastie Boys.

But Costello now is on his first set of headlining solo dates on the east coast in a decade, and reviews have raved: from "Mesmerizing" and "Spellbinding (OC Register) to "Impassioned" and "Breathtaking" (Arizona Republic) to "altogether stunning" (San Diego Union Tribune).

Costello still is collaborating. His most recent disc, “Wise Up Ghost,” released in September, paired him with The Roots.

Phil Lesh & Friends has been one of the most enduring incarnations of The Grateful Dead side projects – starting when the band was still together as an unplugged version, with members Lesh, Jerry Garcia, Bob Weir and Vince Welnick.

It’s gone through years as a harder-rock band with members such as Warren Haynes, Derek Trucks, Jorma Kaukonen, Jimmy Herring, Robben Ford and members of Phish, Little Feat and The String Cheese Incident.

Since 2012, the band’s back to many of its old members appearing alongside a few new ones.

THE PRETTY RECKLESS, 7 p.m. Nov. 10, with Heaven's Basement and Empire Escorts, Theatre of Living Arts, 334 South Street, Philadelphia. Tickets: $19 general admission, www.ticketmaster.com, 800-745-3000.The Pretty Reckless sure seemed like a celebrity rock group vehicle for actress Taylor Momsen when it formed in 2009. And early on it got far more attention for the then-underage actress’ antics. But after its debut disc, “Light Me Up,” in 2010 hit the Alternative Top 10, and new songs for an upcoming disc, “Going To Hell” showed even more promise, even critics must admit there may actually be something there.

MATT WERTZ, with Elenowen, 7:30 p.m. Nov. 10, World Café Live, 3025 Walnut St., Philadelphia. Tickets: $15-$22. www.worldcafelive.com, 215-222-1400.Singer-songwriter Matt Wertz for years was a successful independent artist, with songs of his used in the 2003 move "My Super Ex-Girlfriend" and on the MTV show "Laguna Beach." Then he signed with Universal Republic Records in 2007 and was subsequently dropped. Since then, he’s released five CDs and an EP on three different labels, all of them consistently good. The latest is “Heatwave,” which came out Aug. 27 and also has him producing. The first single, “Get To You” is a slice of wonderful ‘80s-influenced pop that leaves no question why Wertz was successful in the first place.

JOHN J. MOSER has been around long enough to have seen the original Ramones in a small club in New Jersey, U2 from the fourth row of a theater and Bob Dylan's born-again tours. But he also has the number for All-American Rejects' Nick Wheeler on his cell phone, wrote the first story ever done on Jack's Mannequin and hung out in Wiz Khalifa's hotel room.

She's no expert, but enjoys it all — especially artists who resonated in her younger years, such as Crosby, Stills, Nash and Young, Tracy Chapman, Santana and Joni Mitchell.

KATHY LAUER-WILLIAMS enjoys all types of music, from roots rock and folk to classical and opera. Music has been a constant backdrop to her life since she first sat on the steps listening to her mother’s Broadway LPs when she was 2. Since becoming a mother herself, she has become well-versed on the growing genre of kindie rock and, with her son in tow, can boast she has seen a majority of the current kid’s performers from Dan Zanes to They Might Be Giants.

STEPHANIE SIGAFOOS: A Jersey native raised in Northeast PA, she was reared in a house littered with 8-tracks, 45s and cassette tapes of The Beatles, Elvis, Meatloaf and Billy Joel. She also grew up on the sounds of Reba McEntire, Garth Brooks and Tim McGraw and can be found traversing the countryside in search of the sounds of a steel guitar. A fan of today's 'new country,' she digs mainstream/country-pop crossovers like Lady Antebellum and Sugarland and other artists that illustrate the genre's diversity.
